The thickness of a hollow wooden cylinder is 2cm. It is 35cm long and its inner radius is 12cm. Find the volume of the wood required to make the cylinder, assuming it is open at either end.

Explanation

To find the volume of wood required to make the hollow wooden cylinder, we can follow these steps:

### Step 1: Identify the given values
- Thickness of the cylinder (t) = 2 cm
- Length of the cylinder (h) = 35 cm
- Inner radius (r_inner) = 12 cm

### Step 2: Calculate the outer radius
